1971 Honda CB350K3 · Pistons, Rings & Clips Buying guide

Confirm the bore before choosing standard pistons

The useful distinction is between a complete one-piston kit and a separate pack of pin clips. Neither tells you whether an old engine still has standard bores; that decision needs inspection and measurement.

One kit means one piston

The standard kit includes the piston, matching rings, pin and clips for one cylinder. For a twin-cylinder rebuild using standard pistons throughout, that means two kits. Have both bores measured before buying so the parts match the engine’s present condition.

Use separate clips for a separate need

The additional pin clips come in a pack of two and have a 15 mm specification. They are useful when the job calls for clips separately, but the complete piston kit already includes clips. Check the pin and piston arrangement before ordering a replacement pack.

Buying questions

Can I choose standard pistons from the model year alone?

No. A 1971 engine may already have been rebored or may need machining now. Measure the cylinders and decide the required piston size with the person carrying out the rebuild before placing the order.

Are rings and the piston pin included?

Yes. Each standard kit supplies one piston with rings, a pin and clips. It is a one-piston package, so two kits are needed for both cylinders when standard size is suitable.

Do I need extra pin clips with the complete kit?

The complete kit includes clips. Buy the separate two-clip pack only when your work requires additional compatible clips, rather than automatically adding it to every piston-kit order.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
